Gun Misnomers

Gun Misnomers

As I was enjoying my Independence Day with a few of my close friends we started talking shop and about the weapons we had been working with lately when someone for the group near us over heard us talking about the AR-15 platform and they came over and asked what does the AR stand for? and he told us he had heard it stood for “Assault Rifle” and and we went on explaining where AR came from.

We had a guest posted planned for today but had a problem with getting it sent and up on the site in time so we will just keep working on that and hope for later on this week. so as I rushed to make sure there was a post up for today I thought back on the misinformation that had been given out to our new friend and new reader of the blog and figured today would be a good day for clearing up some misnomers

AR (AR-15, AR-7, AR-10…): The “AR” designation comes from the name of the company that produced the firearm – Armalite. It is a common misconception that it stands for “assault rifle.”

Assault Rifle: This is one of the terms that seems to have shed some bad light on AR-15 weapons. The definition of Assault Rifle that stand out the most is an Assault Rifle must have selective fire meaning you have a switch on the weapon that lets the shooter go from safety  to semi auto to 3 round burst or full auto. meaning that one pull of the trigger lets the weapon function in one of the selected modes.

The standard AR-15 model that is sold is only Safe and Semi-auto fire.

Magazine vs. clip:
A magazine is an ammunition storage and feeding device within or attached to a repeating firearm.

A clip is a device that is used to store multiple rounds of ammunition together as a unit, ready for insertion into the magazine or cylinder of a firearm.

I checked with Knight’s to see if they were planning on releasing the semi-auto civilian model and at this time they are not.

The weapon has ambidextrous controls, It operates on a proprietary dual gas piston system and uses a full curved magazine. (at this time I have been unable to find out if it uses proprietary 6x35mm magazines or if it will use the standard AR platform .223/5.56NATO magazine.)

The KAC PDW (Personal Defense Weapon) uses and was designed around the proprietary 6x35mm cartridge made by Knights Armament. It was designed as a weapon for aircraft crews,  tank crews and truck drivers who did not need to carry a carbine but a small standby small arms weapon should they come under attack while not in transit. This weapons has high lethality of up to 300 meters.  

The PDW with the 6x35mm has as much Kinetic energy as a 10 inch M4 carbine but has 50% less recoil than a standard M4 carbine. The KAC muzzle device is designed for weapon control, it eliminates muzzle climb and recoil, but not muzzle flash.

For all the the AR platform lovers who have seen just a small number of different configurations we have posted on this site here is another.

The FN P90 changed the design of their magazine to be on top of the weapon to keep the rifle in a small neat package to be a PDW but still allow for a large number of rounds to be loaded in the weapon.

The AR-57 upper simply replaces the standard  5.56/.223 upper and since the magazine is top mounted like the FN P90 keeps the weapon small while having the ability to to hold up to a 50 round magazine and not have a long magazine protruding from the weapon.

The magazine is the same as on the FN P90, depending on state and local laws for magazines modified magazine are available in 5 and 10 round set up.

I wrote earlier this week about the AR platform and how much it can be reconfigured with seemingly limitless possibilities and there is really not other rifle on the market with such a versatile design out there.

AR-15

For years I have had my own views and opinions on the M-16/M-4/AR-15 platform and the .223 Remington/5.56NATO rounds and have shot a fair number of different AR-15s.

I like the style of the weapon the look of the weapon and the ease of use.

Over the years I have seen how interchangeable the whole weapon system is and how a simple push of two pins can change the weapon from firing a .223 to a .50 BMG or a change of the bolt can make it fire a .22LR.

The AR platform can be configured to a good number of different calibers such as: .20 Practical, 22LR, 5.45×39, .223, 5.56NATO, 6.5mm Grendel, 6.8 SPC 7mm TCU, .300 Whisper, .300 Blackout, .338 Lapua, .40 S&W,  10mm, .45 ACP, .450 Bushmaster, .458 Socom,
.499 LWR, .50 Beowulf,  .50 BMG, 7.62×39 just to name a few

The upper can be changed to make the weapon a shotgun, a belt-fed weapon, fire pistol rounds or just be reconfigured into a short pistol style weapon.

The versatility that the AR platform offers to the shooter is almost limitless and with more and more companies designing uppers and various other parts the next few years will make it limitless.

Kel Tec PLR-16

Kel Tec PLR-16

Calibers: .223 Remington
Weight unloaded: 3.2lbs
Length: 18.5″
Barrel length: 9.2″
Twist: 1:9″
Magazine: AR-15 compatible detachable box magazines (STANAG Magazines)
Trigger pull: 5.5-7.5lbs
Action: Gas-operated
Muzzle velocity: 2600fps
Effective range: 400 m

The Kel-Tec PLR-16 (Pistol, Long Range) gives the shooter the a .223 rifle in a compact pistol/PDW design.

This weapon is small enough to be carried in a leg holster. The nice thing about the Kel-Tec is it lets the shooter use the same magazine in both an AR and this gun so you don’t have to buy all new magazines if you want more than what comes with the weapon.

plr-16

The PLR-16 uses both the multi-lug rotating bolt design and breech-locking system similar to the AR-15 with a gas piston system like that of the AK-47 and M-14.

Specs

Caliber: .458 SOCOM
Barrel: 16” Chrome Moly Bull Barrel, 1:14 R Twist
Action: Semi-Auto AR Platform
Overall Length: 36”
Weight (empty): 7.6 pounds
Magazine: Standard .223 AR-15 Mags

SOCOM (Special Operations COMmand) contracted out for a new project which was brought on by a lack of power that the 5.56NATO cartridge has in the M4 and the M16.
SOCOM set a number of specific requirements for this new weapons system such as that the round must fit the standard M4 – M16 Platform and standard magazine and be capable of firing heavy-for-caliber projectiles at subsonic velocity using suppressors.

Marty ter Weeme, founder of Teppo Jutsu LLC. designed the cartridge in 2000 and Tony Rumore of Tromix, Inc was contracted to build the first .458 SOCOM rifle for use in February 2001.

In the developments phases, there were various other cartridges that were considered and proposed to the project sponsor, but rejected as not meeting all the requirements. The cartridges considered were 7.62x39mm, 9x39mm Grom, .450 Bushmaster, and .50 Action Express.

The .458 SOCOM uses the standard AR mag but due to it size does not allow for double stacking the rounds and subsequently only lets the mag hold a fraction of the rounds.

  • 10 rounds Magazine designed for .223 will hold 3 rounds of .458 SOCOM
  • 20 rounds Magazine designed for .223 will hold 7 rounds of .458 SOCOM
  • 30 rounds Magazine designed for.223 will hold 10 rounds of .458 SOCOM
  • 40 rounds Magazine designed for.223 will hold 13 rounds of .458 SOCOM
  • The 90-round .223 drum can hold as many as 33-36 rounds of .458 SOCOM
  • The 100 round beta mag will not work.

The AR-15 platform chambered in the .458 SOCOM gives a hunter a lightweight rifle with in  heavy caliber  that is durable and well suited for large game hunting.

Bushmaster ACR

Bushmaster ACR

bushmaster-remington-acr

I know I am going to catch some flack from writing about the ACR before I write about the FN-SCAR but I’m okay with that because no one requested the SCAR.

SPECS

Caliber: 5.56 – 6.8 SPC II
Barrel: 10.5” – 14.5” – 16.5”
Trigger: Standard AR/M-16 trigger, 4.5 – 6lbs, Match trigger available
Magazine: Accepts MagPul PMAG and Mil-Spec M-16
Weight: 14.5 Weapon, Base rifle – 7lbs 14oz, Loaded w/ suppressor – 9lb 13oz
Length: 14.5 Weapon, W/o Suppressor, Stock folded – 25.75”, W/o Suppressor, Stock deployed – 32.625”, W/o Suppressor, Stock extended – 35.5”

Bushmaster has announced plans to make the ACR in 6.8 SPC and 7.62x39mm.

The ACR stands for Adaptive Combat Rifle and is easy to interchange the caliber of the rounds this rifle shoots with THREE simple changes, the barrel, the bolt carrier, and the magazine.

remington_acr

This weapon has a few variations such as barrel lengths and calibers, the color schemes, Stock made of polymer or metal, Lower receiver made of polymer or metal.

This system truly lives up to its name as an adaptive rifle for the end user.

(Update) On October 15, 2010 Bushmaster issued a recall of all ACR rifles instructing users to “Please immediately discontinue the use of your ACR rifle” along with instructions to contact customer support for an RMA. Bushmaster stated that the recall was issued due to “a possible firearms performance issue that may develop with a small number of ACR rifles” and goes on to state that “Bushmaster discovered a design flaw which could result in multiple rounds firing continuously when the trigger is pulled”. Bushmaster has stated that it will cover all of the costs associated with the repairs to the recalled rifles [wiki]

Promag magazine vise block

PM123-2T

Here is something I think is pretty nice if you ever have to work on your AR or if you are planning on building an AR. The vise block lets you work on your AR locked in a vise so your gun doesn’t move.

The block is made with a durable black polymer so it will hold up to years of use and is designed after the standard AR-15 .223/5.56NATO magazine and just slips into the mag well and locks in using the rifle’s magazine catch.

This is the new Sig Sauer 716. this rifle is designed after the AR-10 rifle and they are making 4 sizes of this Rifle all chambered in .308 Win / 7.62NATO.

They are making Semi-auto version of all four rifles for purchase in the civilian market.
The release dated has yet to be announced.

I will be excited when the I can read the reviews of this rifle after it has been fielded. This rifle is against some heavy hitters such as the M110 or the AR-10.

AR_mag_vault_w-key_3

I was talking to someone the other night about the AR platform and they were asking my take on the rifle and how far it has come since its introduction into the US military in 1963 and long story short he asked about locking the gun up and after talking a bit about a gun safe he asked about locking the weapon itself up so it couldn’t be loaded with a magazine.

Now this got me thinking about the locks on the market I had seen and most of the ones I had looked at were cable locks and so I figured I would look and see what was out there for the AR and this was one I liked for the shear fact it slides into the mag well and also blocks the barrel from loading of a round.

mag_vault_in-AR_view2_2

This is the GunVault AR MagVault Rifle Lock. the price online isn’t bad and I like that is a bright orange so it is clearly visible when the weapon is just sitting there.
